Strange

it is very clear....a linear function is of the type y=ax+b

replace x = 1000 and then x = 2000 and solve the system ...to find a and b

you must find y=x/100 + 25....it is simple. - Apr 4th 2013, 02:31 AMstrangepathRe: Coordinate Geometry

There is atyping mistake, when x = 4000 we get y = 65. By mistake i typed x twice. Sorry. Now it should be clear
